The 25-year-old model and the magazine mogul, 85, called off their wedding this week, just five days before they planned to tie the knot in front of 300 family and friends. While The Snitch Circuit is alive with whispers that Crystal used Hef to promote her new pop single, “Club Queen,” and that the busty blonde’s been secretly sleeping with Dr. Phil’s son, Jordan McGraw, Harris called into Ryan Seacrest’s AM radio show — “On Air with Ryan Seacrest” — Wednesday to put the kibosh on the goss.

“It was mutual between Hef and I,” she told Ryan. “There was no fight, we sat down and we talked about it…For a while I’ve been having second thoughts about everything. I haven’t really been at peace with myself lately. I didn’t think it was really fair to him.”

Though Crystal and Hef have been dating for nearly two-and-a-half years, the centerfold says her ex’s idea of wedded bliss doesn’t exactly jive with her own.

“Hef’s lifestyle isn’t the most normal lifestyle. Multiple girls all around, it’s not the lifestyle I wanted,” Harris explained.

In spite of his trail of tears on Twitter, the former Almost-Mrs. Hefner says America’s Horniest Octogenarian is taking the slight in stride.

“..He was doing it for me because he thought it was what I wanted. He was just doing this wedding for me.”
